In ventricular fibrillation, there is no pattern visible in the EKG. What does this mean in terms of contraction? A. contraction will have no visible pattern either and the ventricles will be unable to eject much blood B. the pattern doesn't matter; contraction of the ventricles will not be affected as long as ventricular myocytes continue to depolarize and depolarize C. the ventricular myocytes will be unable to contract C. contraction will become constant and ventricles will be unable to fill with blood 2. Which structure follows depolarization of the SA Node and atria in the cardiac conduction system?
